Mubadala Investment Company, Abu Dhabi’s sovereign wealth fund, expanded its position in BlackRock’s iShares Bitcoin Trust by 16% during the first three months of 2026, recent SEC disclosures reveal. The fund’s holdings now total 14.7 million shares with an estimated market value of $566 million.
While the share count increased substantially during Q1 2026, the dollar valuation experienced a modest decline from the $630.6 million reported at year-end 2025. This discrepancy stems from Bitcoin’s price correction following its peak levels in late 2025, not from any reduction in Mubadala’s position size.
Five-Quarter Accumulation Pattern by Mubadala
Mubadala’s initial Bitcoin ETF disclosure appeared in Q4 2024 filings, showing approximately $436 million in holdings. During Q1 2025, the portfolio’s market value decreased to $408.5 million due to Bitcoin price volatility, before rebounding dramatically to $630.6 million by December 31, 2025, coinciding with Bitcoin’s climb above the $100,000 threshold.
The wealth fund has methodically expanded its share holdings during each subsequent reporting period. This unbroken five-quarter accumulation pattern demonstrates a calculated, sustained allocation strategy rather than tactical trading behavior.
Mubadala isn’t the only Abu Dhabi institution building Bitcoin exposure. Al Warda Investments, connected to the Abu Dhabi Investment Council, maintained a separate position of 8.2 million BlackRock Bitcoin ETF shares valued at approximately $408 million as of Q4 2025. Together, sovereign entities tied to Abu Dhabi controlled over $1 billion in the ETF by the close of 2025.
The Abu Dhabi Investment Council itself executed a notable expansion during Q3 2025, tripling its Bitcoin ETF allocation in one of the largest quarterly increases documented among sovereign investors.
BlackRock’s iShares Bitcoin Trust maintains its position as the world’s largest spot Bitcoin ETF, with holdings exceeding 600,000 Bitcoin as of April 2026. This represents approximately triple the assets held by its nearest competitor, Fidelity.
Norway’s Norges Bank has also emerged in recent 13-F disclosures as a stakeholder, cementing the ETF’s role as the preferred vehicle for government-level Bitcoin investment.
University Endowments Show Mixed Signals on Crypto
Institutional approaches varied significantly. Harvard University decreased its BlackRock Bitcoin ETF allocation by 43%, reducing holdings to 3.04 million shares. The prestigious endowment simultaneously liquidated its entire $86.8 million stake in BlackRock’s spot Ethereum ETF.
Dartmouth College pursued an alternative strategy. The institution revealed what appears to be among the first university endowment investments in a Solana ETF, acquiring $3.67 million worth of the Bitwise Solana Staking ETF.
Barclays reported ownership of 4.46 million BlackRock Bitcoin ETF shares, complemented by both put and call option positions. Meanwhile, Hong Kong-based investment firm Laurore decreased its holdings by 22%.
The Q1 2026 13-F filing cycle reveals an expanding schism in institutional cryptocurrency strategies. Gulf-based sovereign wealth funds continue methodical accumulation, while certain university endowments are contracting their digital asset exposure.
Mubadala’s uninterrupted accumulation pattern spanning five consecutive quarters represents one of the most transparent long-term institutional Bitcoin commitments from any government-backed investment vehicle worldwide.
